Sulphate-reducing prokaryotes (SRP) have been identified in oil field fluids since the 1920s.
SRP reduce sulphate to sulphide, a toxic and corrosive species that impacts on operational …

Organic and inorganic chlorine compounds are formed by a broad range of natural
geochemical, photochemical and biological processes. In addition, chlorine compounds are …

Carbon monoxide (CO) is a gas that is toxic to various organisms including humans and
even microbes; however, it has low redox potential, which can fuel certain microbes, namely …

Dissimilatory perchlorate reduction is an anaerobic respiratory pathway that in communities
might be influenced by metabolic interactions. Because the genes for perchlorate reduction …

Respiration of perchlorate and chlorate [collectively,(per) chlorate] was only recognized in
the last 20 years, yet substantial advances have been made in our understanding of the …

Dimethyl sulfoxide reductases (DMSO) are molybdoenzymes widespread in all domains of
life. They catalyse not only redox reactions, but also hydroxylation/hydration and oxygen …

Chlorine has important roles in the Earth's systems. In different forms, it helps balance the
charge and osmotic potential of cells, provides energy for microorganisms, mobilizes metals …

Chlorate has become a concern in the food and beverage sector, related to chlorine
sanitizers in industrial food production and water treatment. It is of particular concern to …

Three new strains of dissimilatory perchlorate-reducing bacteria (DPRB), QD19-16, QD1-5,
and P3-1, were isolated from an active sludge. Phylogenetic trees based on 16S rRNA …

Chlorine is abundant in cells and biomolecules, yet the biology of chlorine oxidation and
reduction is poorly understood. Some bacteria encode the enzyme chlorite dismutase (Cld) …
